Chicago-latrobe 41626 Jobber Drill Bit 13/32 in Hss Tin

Product Description

The CHICAGO-LATROBE 41626 is a jobber-length drill bit designed for heavy-duty drilling in ferrous and hard metals. It is machined from high-speed steel with a titanium nitride (TiN) coating, which extends surface hardness and reduces friction during cutting. The 135-degree split point geometry allows the bit to self-center on contact, reducing the need for a center punch on most materials. At 5.25 inches overall length with a 3.875-inch flute, this bit fits standard jobber-length chucks and drill presses used by machinists, pipefitters, and HVAC technicians working with structural materials.

This bit is sized at 13/32 inch (0.4062 inch decimal equivalent) and is suited for drilling cast iron, stainless steel, and structural steel in both fabrication and field service applications. The right-hand spiral flute clears chips efficiently during deep passes. The Series 150ASP-TN designation identifies this as a high-performance, heavy-duty grade bit intended for demanding production and maintenance drilling where standard jobber bits wear prematurely.

Key Features

• TiN coating increases surface hardness and extends tool life in abrasive metals
• 135-degree split point self-centers on contact and reduces thrust force
• Web-thinned, tapered web design improves chip evacuation in deep holes
• Right-hand, regular-spiral flute geometry for consistent chip clearing
• Straight-cylindrical shank fits standard 3-jaw chucks without adapters
• Meets NAS 907 Type B specification for heavy-duty drill bit performance

Compatibility

Designed for use in standard jobber-length drill chucks on hand-held drills, drill presses, and milling machines. Primary workpiece materials are cast iron, stainless steel, and steel as noted in the product specifications.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal-cutting operations. Secure workpieces firmly before drilling and ensure the drill chuck is tightened properly before starting the spindle. Always wear appropriate eye protection and follow applicable shop-safety and OSHA guidelines when operating drilling equipment. Do not exceed the recommended speed and feed for the workpiece material and bit diameter.
